If you only need a tool or piece of equipment infrequently then instead of buying one, save resources by asking a friend or neighbour if you can borrow one. Or check online for a lending club, such as Streetbank.
Use a recycled plastic water butt to collect rainwater for your garden.
If possible replace disposable products with reusable ones (eg. food storage, coffee filters, straws, etc.).
Use beeswax candles instead of ordinary paraffin candles. They burn cleaner, brighter and last longer. They also emit negative ions which improve air quality.
Choose rechargeable batteries and a battery charger to cut down on disposables. Eventually recyclable batteries reach the end of their life too but they can be recycled – local recycling policies vary so check with your recycling facility.
Use dried tea leaves as a deodoriser. Scatter them over the carpet, leave for ten minutes then vacuum up. Place in the fridge to absorb odours (like baking soda).
